Karl, everyone chooses to play the game at the level they choose.... Not necessarily at the level of "every thing in his power"

This is why we have a pecking order in A, B and C fleets. Healthy classes manage all of these factors. The A fleet in the A class frequently have done Olympic campaigns and compete world wide. The B Fleet have won National Championships in other classes... and the C fleet are weekend warriors with modest aspirations in the class.

Healthy classes manage all levels of the sport. In a development class like the A Class, the judgement and experience to manage big jumps in technology are part of the game. This is what Dave is speaking about and he has set his personal standards.
